ABSTRACT:
A light-emitting device including a light-spreading device having a wing-shaped protrusion part, a light-entering surface that includes an uneven surface, and a recess located away from the light-entering surface; an optoelectronic device disposed under the uneven surface and emitting light towards the light-entering surface; and a wavelength-converting material formed on a path along light traveling from the optoelectronic device. The device may additionally include a liquid crystal layer for controlling light flux from the light-spreading device; a color filter layer including a plurality of pixels provided adjacent to the liquid crystal layer. The device may be a liquid crystal display having a backlight module, a liquid crystal layer, and a color filter layer. An ultraviolet unit for emitting ultraviolet light may be disposed in the backlight module. At least one pixel may be filled with a wavelength-converting material that can convert ultraviolet light into green light.
